The spelling of the word "kwedien" can be explained using the International Phonetic Alphabet (IPA). The first sound, "k," is a voiceless velar stop produced by blocking the airflow at the back of the mouth. The next sound, "w," is a voiced labio-velar approximant, formed by rounding the lips and bringing them close to the back of the palate. The following sound, "e," is a close-mid front unrounded vowel produced by raising the front part of the tongue towards the hard palate. Finally, "dien" is pronounced as "dyin," with the stressed syllable being the second one.
